How is an AED operated?

Using an Automated External Defibrillator (AED) effectively involves a straightforward process designed to be user-friendly, even for those who may have little or no medical training. Firstly, turning the AED on activates the device and triggers voice prompts that guide the responder through each step. These prompts provide clear instructions on what to do next, such as applying the electrode pads to the patient’s chest in the correct locations.

Once the pads are in place, the AED can analyze the heart’s rhythm to determine if a shock is needed. This guidance makes it easy to follow, reducing stress during an emergency situation. Every AED is designed to ensure that by following the voice commands and applying the pads correctly, the chance of effectively treating a person in cardiac arrest is maximized.

The other options suggest unnecessary steps or incorrect sequences that could delay defibrillation, which is crucial in a cardiac emergency. For instance, adjusting settings before turning the device on is not standard practice, as the AED is designed to operate in an automated manner without requiring manual tweaks. Similarly, starting CPR before using the AED is appropriate in some context, but once the AED is available, using it as soon as possible is vital to increase the chances of survival.
